First time with Norwegian line but thoroughly enjoyed this cruise with my partner. The ship, cabin, and freestyle dining were all excellent, the itinerary was also good although we declined to go ashore in Santorini because of the nightmare stories about the steps and the cable car wait. We were proved right by many of the passengers who went ashore and came back with their stories about the steps and the donkeys, and the 2 hour wait for the cable car. We spent a relaxing day on board.
Dubrovnic was lovely although the bus back to the ship was poorly organised with people crush trying to get on board the bus.
Piraeus and the trip to athens was very good but hot, we took the hop-on hop-off bus from the port which cost 22 euros each, but there are lots of taxis and other ways to get to Athens and the Acropolis. The bus took us on a tour of Piraeus and then dropped off at the Acropolis where we walked up, there were thousands of people and a long line waiting to pay to get in. We managed to get tickets from a walking tour guide for the same price as entry, 20 euros. This saved us waiting in line for over an hour in tremendous heat. It is still well worth the visit though, the views are brilliant.
Excellent cabin and not too far from the lifts.
